Target boost vs Manifold relative pressure discrepancies
02 wrx logging with tactrix.
Logging target boost (psi relative to sea level) and Manifold Relative Pressure (psi relative to sea level). There is a large discrepancy at vacuum, for example:. target at idle log is -.93 Manifold log reads -6.79 to -7.79 Is this indicating a problem, or am I not quite understanding this?

to convert psi to vacuum, multiply by 2.. so your -7.79 would be -15.58 which is good vacuum.
17 to 22 is recommended, but 15.5 is pretty solid as well. |
